Find out what Metrohm has to offer for the monitoring of the water chemistry in thermal power plants, the wet chemical processing of solar cells and battery electrolytes, or electrochemical measurements of energy storage devices.

Taking high-precision Metrohm ion chromatography to an even higher level of autonomy, the Process IC can connect up to 20 sample streams and provide reliable multicomponent results for superior process control.

Process monitoring: better value in a smaller footprint

Our 202X Series process analyzers can be set up to monitor a wide range of substances and parameters, easily and reliably. The analyzers come in three basic configurations which cover several industries and some of their most important process applications.

The 2026 Titrolyzer applies titration – a well-established absolute analytical method that does not need calibration.

The 2026 pH Analyzer is used for batchwise pH measurements in situations where inline pH measurements cause problems.

The 2029 Photometer, on the other hand, uses colorimetry and is capable of measurements in the low ppb range.

2026 Titrolyzer

The 2026 Titrolyzer is used for titrations and ISE measurements.

Titration is an absolute analytical method, offering high selectivity through the use of dedicated electrodes and titrants, with no need for calibration. The titration method is suitable for a variety of proven standardized and regulated methods covering a huge number of wet chemical applications. The 2026 Titrolyzer can be your partner to secure the safety of your water sources and be an integral part of improving your process.

Several markets are a perfect fit for the 2026 Titrolyzer such as chemical, petrochemical, semiconductor, mining, steel/metal, and potable water.

Applications in the spotlight:

Sulfuric acid

Sulfuric acid is determined by titrating with sodium hydroxide (NaOH). The detection is done with a Metrohm pH glass electrode. The analyzer is able to handle a wide range of acid concentrations, from mg/L to %.

Hydrochloric acid

Hydrochloric acid is determined by titrating with sodium hydroxide (NaOH), or alternatively with sodium carbonate (Na2CO3). The detection is performed with a Metrohm pH glass electrode. The analyzer is able to handle a wide range of acid concentrations, from mg/L to %.

Hydrogen peroxide

H2O2 is determined via potassium permanganate titration. The detection is performed with a Metrohm platinum electrode. The analyzer is able to handle a wide range of H2O2 concentrations, from mg/L to g/L.

2026 pH Analyzer

The 2026 Titrolyzer configured for pH measurements is the perfect instrument for situations where inline pH measurements fail.

With the 2026 Titrolyzer, temperature, pressure changes, streaming potential effects and more have no influence on the measurement. The electrode condition is continuously monitored, and calibration and cleaning is done automatically. This results in less maintenance, longer lifetime of the pH electrode, and more reliable measurements.

Potential hazards and safety concerns regarding critical pipeline sample points are removed as the electrode does not need to be retracted for tasks like cleaning. You never have to worry about the membrane drying out since the electrode is always immersed in liquid.

2029 Process Photometer

Based on proven laboratory methods, the 2029 Process Photometer can measure in the low ppb range.

The heart of the 2029 is its high performance thermostated LED photometer module capable of measuring the slightest color changes resulting in low detection limits. Such low detection limits are achieved using differential measurements to eliminate for example sample turbidity. The thermostatic cuvette removes temperature fluctuations that have a severe effect on the final result, providing you data you can count on.

The 2029 Process Photometer meets the needs and expectations of several branches like chemical, environmental, semiconductor, petrochemical, food and beverage, potable water, and energy/power.

Copper (I & II)

Copper is determined photometrically based on the Bicinchoninate method, measured at a wavelength of 550 nm. The analyzer is able to handle a wide range of Cu(I & II) concentrations, from μg/L to mg/L.

Custom projects can range from a single analyzer in combination with a simple sample panel to complete packages including multiple analyzers, shelters, piping, wiring, and interfacing. Shelters and other specialized protection solutions can be custom-built upon request.
